DigiTech
Whammy 4
Pitch Shifter
Classic pitch-shifting pedal with expression control for real-time dive bombs and harmonies.
DigiTech, founded in 1984 in Utah, pioneered digital effects processing and became synonymous with pitch-shifting through the Whammy series introduced in 1989.
The Whammy 4 became a pedalboard staple for its expressive real-time pitch control. Sweep through two octaves up or down, create harmonies, or nail dive-bomb effects made famous by countless rock recordings.
The rugged expression pedal allows precise pitch manipulation from subtle vibrato to extreme shifts. Multiple modes cover pitch-shifting, harmony generation, and detune effects. Requires dedicated 9V 1.3A power supply.
